Four months of real work, then months of sitting idle

Staten Island summers push cooling systems hard from June through September, with afternoons averaging 84°F. That is the stretch your air conditioner has to earn its keep, then it sits unused the rest of the year.

Any new central air conditioner installed here has to meet a federal minimum of 13.4 SEER2. That is the efficiency floor, not a ceiling, and it applies whether you are replacing a unit or putting one in for the first time.

What size air conditioner does my house need?
The right size comes from a load calculation, not the square footage of your house alone. A contractor measures your windows, insulation, ceiling height, and how much sun your walls get, then works out the tonnage from that. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels damp. An undersized one runs nonstop and still can't keep up on the hottest afternoons. Ask for a Manual J calculation rather than a guess based on your old system.
Should I replace the whole system or just the outdoor unit?
In most cases both the outdoor condenser and the indoor coil should be replaced together. They're matched to work as a pair, and pairing a new condenser with an old coil usually means losing the efficiency you're paying for, sometimes voiding the warranty too. If your indoor coil and ductwork are still in good shape and the system is only a few years old, a contractor might replace just the failed part. Have someone look at the whole system before deciding, since the coil's condition and the age gap between the two matter more than which part failed first.
Do HVAC contractors in Staten Island need a state license to work on my home?
Ask to see a license before any work starts, and check that it's current. A licensed contractor also carries insurance that protects you if something goes wrong during the job. A contractor can tell you exactly what's required for work at your address.
